Answer AND Explanation:
Stimulation of the membrane causes it to become highly permeable to sodium ions, which diffuse rapidly to the inside due to the concentration gradient. The inside of the membrane becomes positively charged and the outside negatively charged. The membrane is then said to be depolarized. This constitutes the action potential. The reverse of the polarity of the membrane causes the beginning of repolarization.
Mushu is a definitely answer
Answer:
25%
Explanation:
According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.
This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:
30/120 × 100
= 1/4 × 100
= 100/4
= 25% of the selected seeds are infertile.
